This invention relates to a waterproofing and cementing preparation.

The general object of the invention is to provide an improved preparation which performs a combined waterproofing and cementing function and which is particularly adapted for use in securing covering material to a concrete surface.

A more specific object of our invention is to provide an improved waterproofing and cementing material for use in waterproofing concrete to prevent passage of moisture therethrough and for simultaneously with the same material securing a coating upon the waterproofed concrete.

Another object of the invention is to provide an improved waterproofing material for concrete.

An additional object of the invention is to provide an improved cementing material for cementing linoleum or other material to a concrete floor.

Other objects and the advantages of our invention will be apparent from the following description taken in connection with the accompanying drawing, wherein:

Fig. 1 is a fragmentary sectional view through D a concrete wall showing our preparation being applied thereto;

Fig. 2 is a View similar to Fig. 1 showing the linoleum laid in place; and

Fig. 3 is an enlarged, fragmentary, sectional v1ew.

In the laying of linoleum or similar material on concrete floors diiculty is frequently experienced due to the fact that moisture is present in the floor and either condenses thereon or seeps through the floor. This seepage occurs principally through small voids which occur in the upper surface of the concrete. As a result when I linoleum is laid upon a concrete floor, moisture accumulates beneath the linoleum thus causing the material which secures the linoleum. in place to lose its adhesive properties and also causing the linoleum to deteriorate due to the continual presence of moisture on its lower surface.

Our invention seeks to overcome the difficulties mentioned and in the accompanying drawing we show one installation of our invention wherein a concrete floor is indicated at lil. This concrete floor has an upper surface II which is troweled smooth and this surface has minute upwardly opening holes I2 therein which are somewhat pear shaped. On this surface II we place a coating I3 of our waterproofing and cementing material.

Our material, in its preferred form, comprises a composition of between 70% and 80% coal tar,

(Cl. G-32) 10%, or less, of resin, 1% of carnauba wax, 1% pine tar oil, approximately 4% of coal tar derived solvent naptha of the medium commercial grade and not over 10% of asbestos ber with a portion of the fiber of short length and 5 the remainder of the ber of long length.

As one specific composition of our material we employ the following: '76% coal tar, 10% resin, 1% carnauba wax, 1% pine tar oil, 4% solvent naptha, 5% asbestos fiber, 3% long Canadian aslo bestos ber.

In making this preparation we preferably make a preliminary mixture by taking a small amount of the coal tar and heating this and adding the resin and carnauba wax and stirring the mixture so that the resin and carnauba wax dissolve.

The remaining material may then be added to the preliminary mixture while the preliminary mixture is warm or the preliminary mixture may be allowed to cool and the remaining ingredients may be added to the cooled preliminary mixture.

In the use of our material the coal tar acts as a binder and waterproofing agent. The solvent naptha acts as a penetrator while the asbestos serves as a binder. The pine tar oil may be omitted but when used is employed as a deodorizer for the coal tar while the resin serves as an adhesive and the carnauba wax serves as an anti-crystallizer for the resin. The short asbestos bers furnish a body for the material while the long fibers provide body and tensile strength to the material.

After the preparation is made it is applied as shown in Fig. l and it is of such consistency that it enters the apertures or holes I2 to the upper surface thus forming small projections which serve to hold the preparation in place and which also, of course, have a waterproofing effect on the concrete floor. After the preparation is in place a covering of linoleum I4 islaid and firmly pressed into intimate engagement with the preparation so that the parts become rmly united and due to the waterproofing effect produced water does not rise through the concrete so that the lower surface of the linoleum remains in good condition.

In Fig. 3 we show an aperture I2 enlarged and show the asbestos fibers at I5 thus indicating the manner in which these fibers serve to unite the materials.

From the foregoing description it will be apparent that we have invented a novel waterproong and cementing material which is highly efficient for the intended purpose.

Having thus described our invention We claim: comprising by Weight 76% coal tar, 10% resin. 1. A Waterproong and cementing preparation 1% carnauba Wax, 1% pine tar oil, 4% coal tar comprising by weight approximately 76% coal derived solvent naptha, 5% ne asbestos ber, tar, 10% resin, 1% carnauba Wax, 1% pine tar 3% long Canadian asbestos fiber. 5 oil, 4% solvent naptha and 8% asbestos fiber.
